ThisV invention relates to internal combus,y

tion engine radiators, .and particularly to employed on automobiles or othervec Generally stated, fthe object of the invention is to provide a novel and improvedconstructionwhereby repairs can bemade in an easy and more satisfactory manner than heretofore, by the removalof any tube alone and without Athe necessity of detaching other tubes, whereby the possibility of damage by freezing will be reduced,-and "whereby more 'v satisfactory results will be l.ensured f than heretofore in the operation and usejolf radiators lior this purpose. x y It is also an object to provide certain details and. features ot' eon-stru'ct-ion and ornbinations tendlng `to increase the general Aeifv ficiency and the desirability of a radla'tor the-invention consists in matters hereinafter!-r 'V set' forthand shown, in the accompanymg construction of this Aparticular character.

As thus illustrated the invention comprises a pair of upper headers l and 2 and a pair of lower headers 3 and 1i arranged transversely of the automobile or other vehi-` cle andclamped together by bolts 5 which through the lower headers'. In addition side plates 'i' are fas tened to theA upper and lower headers by .f screws 8, so that the structure' as a `whole "is strong 'and rigid. Rin

9 are interposed betweenthe headers 3 an 4, to provide connection between the two headers-.and similarv rings 210 are interposedfbetween the twoA u pper headers, for thesame purpose, where by the radiator ,as a whole is .composedof frontfand rear sections bolted to ether and! provided withmeans of commumat'ion between them. The header 2 has an inlet boss".

ilthfor the inlet,pipe l2 leading from `the engine i3, andthe tower header 4 has ran outlet bess ltior the outlet pipe l5' which leads back to said. engine, softhat the'water enters the radiator at the top and leaves at the bottom thereothinthe usual'fmanner. The header l has a ihng cap iti, `which can be removed to ll, the Iradiatorin the usual manner. A tubular portion 'i7 extends vdown from said cap and' is previded. with lateral inlet vopenings i8 near the lower end yt.`t1ereof. A float valveig is movable up of the radiator. In other Wordspthe ra' diator can only beltilled to a certain height,

ings 18 nozturthervvater can enter 'the radiator from lthe` tubullar portion -li' which constitutes a ortion ot the iiin' means. In this way, t erefore, space is ie in the headers i and 2 for expansion ofthe water when it is heated,` or 'when it boils, inasmuch as the `water can alwa s expand into the upper headers. The hea ers can he similarl formed, so that additionai headers can e incor orated in the lradiator structure, if ad itional radiating surface is needed. As shown, there are two headers atthe 'top and two headers at 'the bottom, but it is obvious that three or four or any desired number-of headers can be arranged one in front of the other at the top, and also at the bottom, if a larger radiator is required. ;As the cireuiating system 'thus provided is entirely closed, so'that noV leakage `can occur, there will be no loss ot "Water or shown more clearly in Figures i and 5, so that the radiating surface is increased, and 'the tubes can be made 'of' quite thin metal,

inasmuch as a solid-filler 25 is provided in Seach tube, to prevent 'the iatter 4'from buck ling or becomin distorted ina-ny way. The

ller 25, it will e-seen, as-shownin Figure 5,I 1s crossshaped n--transverse section, so

e seen, are provided with hollow circumferential.. anges 24, as

as after the float. valve 19 closes the lopenfill to force the `internal edges of the tube into' that it provides 1tour grooves or passages 'for the downwardliow of the water throughthe flanged or corru' ated sheet metal tubes .which are thus he d in position without any solder or packing, whereby said tubes can eac-h be readily removed laterally,` without disturbing or disconnecting ,other ltubes when itis desired to 'make repairs. As shown 1n Figure 5 the ends of these,r tubes are bent inward at 26 'to engage a groove 27 on the tapered boss 28 ofthe radiator. A collar 29 which is internally tapered is employed said roove. The collar 29 can be forced in position in any suitable or desired manner, thus for-ming a tight joint between the tube and the header. In Figure 4 the screw threaded rinff- 30 is employed to force the out-turnedjed ges 31 of the sheet metal into the recess 32 in the header, so that the tube is forced on tothe tapered'boss 33 of the header, thus forming a tight joint between the tube and the header. Obviously, howi ever, various constructions can bev employed for providin tight joints between the tubes and the hea ers in such a manner as will that the opposite ends of each bolt are pracpermit ready removal of the tubes,by lateral removal. of any tube alone; as shown, when such isnecessar' or desirable.v `Referring to Figure 3 it wil be seen lthat the tubes 20 are staggered on each header, there being two rows of tubes vextendingv along each header, and the members of one row alter- 3'5 nating with the members of the other row,

so that they have the desired staggered arran ement. This, it will vbe seen, serves to s faci itate the making of re airs, inasmuch as inner rows of tubes are t ereby rendered vmore accessible.- Furthermore, the stagpressure may escape to afford relief in case the pressure does become too great within the radiator. v i

It will be seen that the bolts 5 and 6 have their opposite heads countersunk inV the cavities 35 formed in. the header sections, so

tically Hush with the vertical surfaeesof the headers. Furthermore, it will be seen that' these bolts extend through cylindrical rti'ons 36 which are integral with the hea ers, whereby the bolts can be removed without producinoG any openings through which leakage couldawtake lace. In fact, each bolt is entirely enclos inside the header sections v'means thus formed integral with the hea-der sections, and leakage around the bolt is absolutely'prevented atall points. lWhen Athe bolts are `tightened, the oppositely tapered rings. 9 form tight `oints between the header sections, and no lea age can occur.

herewhen the parts are properlymachined and made and fitted together in the right way, thereby` to' produce the construction shown and'described. It will also be seen that by removing the sideportions 7, after taking out the screws 8, the upper header can be disconnected from the lower header., thereby vto facilitate removal of` any of the vertically disposed radiating tubes. Of course, with theconstruction shown in Figure 2, any tube can be vremoved without disconnecting thefupper'header from the lower header, inasmuch as the unscrewing of the caps 22 from the threaded bosses 23 will permit lateral removal of the tube. However,

as shown in Figuresli and 5 some endwisev contraction of` each tube will be necessary,

not disconnected from the lower header,`and whilethis can be done, of course, it is pos-- sible to take oit the side plates 7 and thereby permit loosening of the different tubes in a `way that will facilitate their. removal when necessary or desirable.

The said tubes are- .for its removal, if the upper header were made of sheet metal and are of such form thatr they are. laterally flexible, and might warp or bend out of shape, except forthe Y provision of the element-s 25 previously described, these elements being stiff and rigid los ible, are held stiiiiy upright in position, and

are vheld against lateral fiexin or bending, as shown, preferably by the stiffening members 25 enclosed therein. In each case, it will. be seen, these stiifening members 25 are not long enough to extend into the headers, but are only long enough to just barely extend from one boss 23 below to the boss 23 above, or from ,one boss 28 below to another boss 28 above,- or fromone boss 33 below to another similar boss above, whereby these stiifening members 25 are individuallylatterally movable with their tubes without disturbing the balance of the structure, as shown and described. In Fig.l 2 the rings 22 when unscrewed will permit 'lateral removal of the tube'and its stiffening member without in any way disturbing the balance Aof the structure; and in Fig. .5, the axial displacement of the rings 29 above and below, l and some endwise contraction of the sheet metal tube w ill permit lateral removal of the tube andits stiening member 25 without disturbing any of the other tubes, and

Leashes thisis also true in Fig. 4, for here the unscrewing ofthe rings 30 above and below, end some endwise contraction of the sheet metal tube,will immediately permit lateral removal of the tube and its interior stiilening member without 'the necessity of disconnect-y ing or detachingany of the yother tubes.
